Solstice Promo! Get Sol: Sun Clock for free. 24 hours only.

Our 4.5 star rated app Sol: Sun Clock regularly sells for $3.99 on the App Store, but for 24 hours (starting now) you can get it for free! It’s our way of celebrating the winter solstice, the shortest day of the year, often observed as the beginning of a new year, and thus the basis for many seasonal holidays (including Christmas, which was established on the date of the pagan solstice holiday Sol Invictus).

Note: Yes, we do realize the Solstice isn’t until December 21—at precisely 4:12 PM Greenwich Mean Time, in fact—but the App Store is undergoing maintenance between Dec. 21 and 28, so we’re doing this a couple days early. Also, for all of you penguins in the Southern Hemisphere, it’s actually the summer solstice—the longest day of the year.
